A train slowly drove into the railway station of Biquge www.biquge.info Town, Gao Jianguo and Li Ming and several members of the Standing Committee of the Military Commission stepped down from the train, they got on the jeep parked on the platform, and drove all the way to the company's big airship project research center in the north of Biquge www.biquge.info Town.

Today is the day of the test flight of the company's first soft airship, and Liu He specially called and invited several members of the Standing Committee of the Military Commission. For the test flight of the first airship, Gao Jianguo, Li Ming and others attached great importance to it, and rushed to the town of Biquge www.biquge.info very early today.

As soon as a few cars drove into the research center of the big airship project, they saw that the huge steel structure workshop was full of people standing outside. Liu He and a group of experts and technicians saw Gao Jianguo's vehicle and came over to greet them.

As soon as Gao Jianguo and Li Ming got out of the jeep, Liu He greeted him and said with a smile: "Old Gao, you guys are here early." ”

"Haha...... We all wanted to see the company's first airship, so we came early. Today's weather is not bad, so the test flight should be fine. ”

Liu He nodded and said, "It's absolutely no problem, it's just that now the airship is doing the final inspection work in the workshop, and it is estimated that it will have to wait a little longer." ”

They walked and chatted until they came to the door of the factory. Liu He introduced to everyone with a smile: "This soft airship, named No. 1 real yàn airship, is mainly to collect various real-time flight numbers of airships in the air. The volume of the airbag is 980 cubic meters, including two auxiliary airbags with a volume of 240 cubic meters.

The total length is 35 meters, the diameter is 7.8 meters, the design speed is 72 kilometers per hour, the ceiling is 2,000 meters, and the maximum endurance is 48 hours. Flanked by two 75-horsepower engines in the airship pod, power units converted from our stock UAZ-469 Jeep stock engines with deflectable ducted fan-type propellers.

The way an airship controls buoyancy in the air is very similar to how a submarine controls buoyancy in water. Auxiliary airbags serve the same purpose as pressurized water tanks and are used to contain "heavy" air. When the small airship takes off, the pilot releases the air in the air bag through the guò air valve. Hydrogen causes the small airship to be positive buoyant relative to the surrounding air, so the small airship will rise. The pilot slows down the engines and adjusts the elevator to make the small airship fly at an angle.

The outer skin is made of nylon silk fabric that we brought from the modern world. With good air tightness, the Ministry of Chemical Industry has also studied a paint that is applied to the surface of the outer skin. It plays the role of flame retardant and increases strength. ”

Gao Jianguo said with a smile: "Listening to your introduction, this airship is good." I thought it was just a little airship. It turns out that he is also a big guy. How many people can this airship hold? ”

Liu He shook his head and smiled bitterly: "This can only be regarded as a small airship, there are two pilots in the pod, and it can also carry 2-4 additional passengers." The original plan was to make a small single-engine airship, but in order to collect a detailed number of flight tests, I simply went directly to the twin engines, and the www.biquge.info of Biquge should be considered not low.

Now the research and development work is very smooth, and many technical difficulties have found breakthroughs. If the performance of the No. 1 test airship meets the design requirements. After collecting the real yàn number jù. In the next step, we are preparing to develop a semi-rigid test airship with a wooden frame. ”

Li Ming thought for a moment and asked, "After you have collected the test numbers, this airship should be handed over to the Air Force Department, and I wonder if the ground maintenance work of this airship will be very troublesome." ”

Liu He nodded and said, "The collection of the various flight test numbers is estimated to take several months. The ground maintenance of the airship is much simpler than that of the aircraft, but the lift-off, landing, and tethering storage work requires at least 8 people to assist in the work. ”

At this moment, the two doors of the steel structure factory in front of them were pushed open, and a truck slowly drove out of the factory with a cigar-shaped airship, the head of which was tied to the top of a four-wheeled steel support. Li Yuancong and Ding Weiguo of the Air Force Department. and experts and technicians from more than a dozen R&D centers, are following around the airship.

The truck dragged the airship to a square outside the factory, and a group of technicians made final preparations on the edge of the airship. Li Yuancong and Ding Weiguo of the Air Force Department came to Gao Jianguo and Li Ming to salute. And they were debriefed.

Gao Jianguo said with a smile: "Who is the pilot of this test flight?" ”

Ding Weiguo immediately stood up and said loudly: "Report to the commander, I am the pilot of this airship test flight. ”

"Since it is Xiaoding, then we can rest assured, and we must pay attention to safety after liftoff. By the way, have you prepared safety precautions for this test flight? ”

Li Yuancong, who was next to him, said loudly: "We have been familiar with the two engines on the ground for a long time, and even if one engine has a problem after liftoff, we can use the remaining engine to land safely." In addition, we have a parachute for each member of the airship pod, in case of an accident. You can skydive at any time. ”

After more than half an hour of careful inspection, the test flight of the airship also began. Ding Weiguo and two technicians from the R&D center. Take off with the airship. Ding Weiguo saluted everyone and turned around and boarded the airship pod.

With the roar of two engines rang out. The propellers in the two modified ducts also began to spin. Ground workers remove the steel bracket mooring columns. A ground staff made an OK gesture to Ding Weiguo in the pod, Ding Weiguo nodded, and then opened the exhaust valve of the auxiliary airbag.

As the air in the large number of auxiliary airbags was quickly discharged, the hull of the airship began to float slowly, the ducted fans of the two engines slowly deflected to a certain angle, and the elevator at the tail of the airship also moved downward.

The huge airship slowly lifted into the air and slowly flew forward. When it flew to a height of several tens of meters, the airship changed direction and flew slowly around the R&D center.

Liu He and a group of experts and technicians nervously communicated with the two technicians on the airship with walkie-talkies, recording the various test flights of various airships. The airship flew around the R&D center a few times, and then began to float upwards at a slow speed.

The people on the ground all tilted their heads and nervously watched the flight status of the airship, which was more than 20 meters away from a small size, constantly changing its direction in the air. Liu He walked over and said excitedly: "The test flight situation is very good, the flight state is very stable, if nothing else, this test flight should be very successful." ”

Gao Jianguo and Li Ming were very happy to hear it, they finally had their own airship. Although it is only a real airship, this first step has finally been taken, and with a good start, will the big airship be far away?

The test flight of the No. 1 airship lasted for more than an hour before it began to slowly land on the square of the R&D center. The staff on the ground cheered loudly, everyone hugged each other and shouted, and they were very excited.

During this time, the pressure on the big airship R&D center, from Liu He to ordinary technicians, was very great, after all, the company invested so many resources, and they have not come up with anything substantial. After all, the moderation within the company has the upper hand, and the rhapsodics also spread some bad remarks from time to time.

The airship landed steadily on the ground, and several ground workers dragged the rope on the airship to attach the bow to the tethering post of the steel support. The three people who participated in the test flight opened the pods and walked down one after another. As soon as their feet touched the ground, they were surrounded by an enthusiastic crowd, and the excited people carried the three of them on their shoulders and cheered loudly.

It wasn't until the cheering crowd dispersed that Ding Weiguo ran in front of Gao Jianguo, first stood up and saluted, and then shouted loudly: "Comrade Commander, Ding Weiguo of the Air Force Department has successfully completed the test flight mission, please instruct!" ”

Gao Jianguo returned a military salute and said solemnly: "Take a break!" ”

Then he laughed and said, "Xiaoding, it's good, you didn't disgrace our military committee." In the process of test flight, you must do your best to familiarize yourself with the various operations of the airship, prepare for the airship to enter service in the future, and strive for the airship to be handed over to the Air Force Department, so that you can immediately form combat effectiveness. ”

If this airship is handed over to the Air Force Department in the future, it will be able to carry out reconnaissance and early warning, theater surveillance, theater communications, and material delivery and delivery with an advanced observation and sighting system and communications system.

To take the simplest example, if this airship is suspended over the theater of operations on the battlefield in the future, the communication systems of various units will not be affected by the complex environment such as mountains and jungles in the future, and will become unimpeded within a few hundred kilometers.

The airship is equipped with thermal imaging equipment, which can still provide troops with real-time intelligence in the theater of operations and all-weather reconnaissance and early warning of the battlefield even in the dark environment at night. In case of emergency, ammunition, field food and other supplies can also be dropped on the ground. Even with a few mortar shells, it can also be used for emergency bombardment.

The news of the successful test flight of the No. 1 airship quickly spread to Vladivostok. The employees of the company are also very excited. Liu He also submitted the next work plan of the airship R&D center to the board of directors of the company, and obtained a majority of the pass.

In order to cooperate with the development of the future airship plan, the Science and Technology Commission, the Ministry of Chemical Industry and smelters and other departments and enterprises have also formulated new work plans. The main task of the Science and Technology Commission is to cooperate with the large airship R&D center to transform the high-power engine and tackle key technologies such as hydrogen airbag outsourcing helium.

With the completion of the second phase of the thermal power plant this year and the development of bauxite in Luzon, the next step for the smelter is to build an electrolytic aluminum plant to actively prepare for the future production of aluminum alloy frames for the big airship.

The recent task of the Ministry of Chemical Industry is to carry out technical research on the coating of the outer mask cloth of the big airship, and in the future, it will develop and produce the outer mask cloth of nylon polyamide fiber for the big airship. Of course, this may take a long time to achieve.

In addition, many enterprises and departments are also involved in the big airship plan, from simple screws and rivets to complex navigation and transmission mechanisms, hundreds of projects will be implemented in the near future. (To be continued)
